SWR is NOT a measure of antenna performance -- it has a small fractional 
dB effect on signal strength (the ability of the rig to put power into 
the line, and the loss in the line). Gain vs frequency and uniformity of 
horizontal and vertical pattern vs frequency are what matter for a 
directional antenna.
